TheEffectsofNiCl2onSpiculeFormation
The Effects of NiCl2on Spicule FormationJessica Ann Billet, Franklin and Marshall, Class of 2000Background and ObjectiveSea urchins exhibit radial holoblastic cleavage, eventually forming a blastula. Shortly after the blastula hatches from the fertilization membrance, the embryo begins gastrulation. Gastrulation begins when the vegetal side of the blastula begins to thicken and flatten. This flat sheet of cells is ca......阅读全文
